To aZZ whom it may concern:

Be it known that I, JoHN'H. NEVILLE, a citizen of the United States,residing at Bay City, in the county ofBay and State of Michigan, haveinvented certain new and useful Improvements in Machines for ShapingWood Articles, of which the following is a specification, referencebeing had therein to the accompanying drawings.

The invention relates generally to machines for shaping bars of wood,and more particularly to a machine especially designed .for shapingcross-arms for telegraph-poles.

These cross-arms are formed from wooden bars substantially rectangularin cross section, and the object of the shaping is to give suiiicientcurvature to the upper face of the bar to cause it to readily shedwater. As a telegraph-pole is gained toreceive the crossarm it isdesirable to leave a portion of-the cross-arm rectangular incross-section, and' the parts, as more fully hereinafter described,

and particularly pointed out in the claims.

In the drawings, Figure 1 is a plan :of my improved machine. Fig. 2 is aside velevae tion thereof. Fig. 3 is an elevation of one of theguide-rollers, showing the feed-chain in the groove thereof. Fig. 4 is aperspective view of the finished cross-arm which my machine produces.Fig. 5 is a longitudinal central sectional view.

A is the frame of the machine, in which are the cuttersB and B,supported on suitable drive-shafts C and G, driven from any suitablesource of power, which I do not deem it necessary to describe.

D andD are adjustable blocks in which the cutter-shafts are journaled,so that the cutters may be adjusted-nearer together or farther apart fordifferent sizes of work. Be-

tween the cutters is a guide-bed E, upon which the work rests during thecutting operation.

G and G are two guide-rollers supported stantially' U-shapedorm and arepivoted upon suitable pivot-plates a at the side of the frame, Theseguide-rollers are grooved, as shown in Fig. 3, and in the groove ofthese rollers runs the feed belt or chain I, which I have shown as asprocket-chain running over the sprocket-wheels J and J at the oppositeends of the machine. The sprocket-wheels J and J are supported betweenpairs of posts K and K, the posts K being pivotally-supported on thepivot-pin L and adapted to be adjusted by means of the adjusting-bolt Lat the lower end, so as to tighten or loosen the chain, as desired. Onthe chain at suitable intervals are the depending hooks or lugs M, whichare adapted to engage with the ends of the blanks or bars N or to engagein .the apertures b therein, which I preferably bore in the bar beforeshaping or planing of the bar is effected.

O is a feed-belt which carries the blank or bar from the boring-machineand delivers it on the inclined guide P. Near the end of this guide isthe stationary guide-roller P, journaled in the adjustable block Q. The

guide-roller P is below the conveyer-chain,

and as the blank is fed by the belt 0 up onto the guide-roller P one ofthe hooks or lugs M on the feed-chain will engage in one of theapertures?) in the blank and continue its mo tion through thelaning-machine. The blank in being fed orward from this point willincline upwardly from its rear end to its in the opposite direction.This reverse tilting of the blank is prevented after a portion of thetravel by'the guide-roller-R, j ournaled in the end of the frame R,which in turn is on thearms H and H, respectively, which 7 arms, asshown in the lan, Fig. 1, are of subforward end, because of its bearingupon the roller P until it passes the middle point, when its weight willtend to tilt it to incline,

pivoted at c on the block Q. This guideroller R, combined with theguide-roller P, maintains the forward end of the blank above the cutterB until the blank has been fed forward sufficiently far so that itsforward end will strike the bed E and then resting on that bed and onthe roller P it will still be free from the cutter B. As soon as theblank strikes the roller G that roller will be slightly lifted, which ispermitted by the hinge-frame H, which supports the roller. The continuedmovement of the blank will finally move the rear end off the roller P,when the blank will drop by its own weight and be held down by theweight of the roller G in contact with the cutterB on the rear portion,(lettered e in Fig. 4,) which will be rounded off. It will be understoodthat the blank is fed forward more than half its length and beyond thecenter or square portion h of the blank before it is allowed to lowerand come in contact with the cutter B. The blank will then be fedforward on the bed E, and its forward end will come in contact with thecutter B, being held in contact therewith by the roller G, and thiscutter will operate on the forward end of the blank until the forwardend thereof strikes the guide-roller T, when the blank will be lifted upso that its forward end rests on the roller T and its rear end on thetable E, and it will be clear of the cutter B. This lifting takes placewhen the portion lettered 'i of the blank has been planed.

It is necessary that the rear end of the blank should be free from thecutter B as it passes thereover, and this I accomplish by means of theguide-roller T, journaled in the open frame U, which is pivoted at onthe adjustable block V and in which is ournaled the roller T. Before therear end of the blank or bar reaches a point where it will contact withthe cutter B its forward end contacts the roller T, and it is deliveredinto a horizontal position, as shown at the left hand of Fig. 2. This ispermitted by the slight raisin of the roller G as soon as the forwardend of the blank strikes the roller T. The blank is then fed out of themachine shaped as shown in Fig. 4.

I preferably provide the frames R and U with the hooks Z, which areadapted to strike the pins m on the blocks Q and V, respectively, so asto prevent any undue jumping or movement of the rollers R and T causedby the blow of the blank thereon.

The blocks Q and V are adjustable to and from the cutters, and inadjusting the blocks the frames R and U, with their respective rollers,are likewise adjusted, so that the device may be adapted for blanks ofdifferent lengths.

In case any of the grab-hooks on the chain should rest over animperforate portion of the blank it will not interfere with theoperation of the device, as the guide-rollers G and G will simply riseat that point; but their weight will still be imparted to the blank atthat point and hold it in contact with the cutters.

The machine described produces the work in a satisfactory and eflicientmanner, is very cheap in construction, and the adjustments are quicklyand easily made for different lengths or sizes of cross-arms. Inasmuchas the guide-rollers R, G, G, and T are all sup-" ment, this difference'in height being taken care ofautomatically by the hinged frames whichsupport the rollers.
